Based on the given dimensions, the area of one wall in the square room is 45 square meters
From the question, the given parameters about the square room are:
Floor area = 81 square meters
Height of the room = 5 meters
The area of a square is calculated using
Area = Length * Length
This means that:
Floor area = Floor length * Floor length
Substitute the known values in the equation
81 square meters = Floor length * Floor length
Rewrite the equation as:
81 square meters = Floor length^2
Take the square root of both sides
Floor length = 9 meters
The area of one wall is then calculated as:
Area of one wall = Floor length * Height of the wall
So, the equation becomes
Area of one wall = 9 meters * 5 meters
Evaluate the product
Area of one wall = 45 square meters
Hence, the area of one wall in the square room is 45 square meters
